Automatic standby mode
Pilot Assist is dependent on other systems, e.g. stability control/anti-skid ESC. If any of theseother systems stops working, Pilot Assist isswitched off automatically. In the event of automatic deactivation a signal will sound and a message is shown in the driver dis-play. The driver must then intervene and adaptthe speed and distance to the vehicle ahead. Automatic deactivation may occur if:
• the speed is below 5 km/h (3 mph) and Pilot Assist is uncertain whether the vehicle aheadis a stationary vehicle or an object, such as aspeed bump.
• the speed is below 5 km/h (3 mph) and thevehicle ahead turns off so that Pilot Assist nolonger has a vehicle to follow.
• speed is reduced to below 30 km/h(20 mph) - only applies to cars with manualgearbox.
• the driver's hands are not on the steeringwheel
• the driver opens the door
• the driver takes off the seatbelt
• engine speed is too low/high
• wheels lose traction
• brake temperature is high
• the parking brake is applied •
the camera and radar unit is covered by e.g.snow or heavy rainfall (camera lens/radiowaves are blocked).
Reactivating Pilot Assist from the
standby mode
NOTE: The illustration is schematic - details may vary depending on car model.
–Press the steering wheel button (1).
> The speed is then set to the most recently stored speed.
NOTE
A marked speed increase may occur once the speed has been resumed by pressing steer- ing wheel button

Change of target and automatic braking with Pilot Assist *
In combination with automatic gearbox, Pilot Assist has functionality for change of target and braking at certain speeds.
Change of target
If the target vehicle in front suddenly turns then there may be stationary traffic in front.
When Pilot Assist is following another vehicle at speeds below 30 km/h (20 mph) and changes
target from a moving to a stationary vehicle, Pilot Assist will slow down for the stationary vehicle.
WARNING
When Pilot Assist is following another vehicle at speeds in excess of approx. 30 km/h
(20 mph) and the target is changed from a moving vehicle to a stationary vehicle, PilotAssist will ignore the stationary vehicle andinstead select the stored speed.
• The driver must then intervene him/ herself and brake.
Automatic standby mode with change of target
Pilot Assist is disengaged and set in standby mode: •when the speed is below 5 km/h (3 mph) and Pilot Assist is uncertain whether the tar-get object is a stationary vehicle or someother object, e.g. a speed bump.
• when the speed is below 5 km/h (3 mph)and the vehicle in front turns off so the PilotAssist no longer has a vehicle to follow.
Automatic brakingFor shorter stops in connection with inching for-ward in slow traffic or at traffic lights, driving isautomatically resumed if the stops do not exceedabout 3 seconds - if it takes longer before thecar in front starts moving again then the PilotAssist is set in standby mode with automaticbraking.
–Pilot Assist is reactivated in the following way:
• Press the steering wheel button
.
• Depress the accelerator pedal.
> Pilot Assist resumes following the vehicle ahead if it starts moving forward within 6 seconds.
NOTE
Pilot Assist can hold the car stationary for a maximum of 5 minutes - then the parkingbrake is applied and the function is disen-gaged. Before Pilot Assist can be reactivated, the parking brake must be released.

Limitations of Parking assistance *
The Parking assistance function may have limita- tions in certain situations.
NOTE
Since a towbar is configured with the car's electrical system, towbar protrusion isincluded when the function measures the dis-tance to an object behind the car.
IMPORTANT
Objects e.g. chains, thin glossy poles or low barriers may be in the "signal shadow" andare then temporarily not detected by the sen-sors - the pulsating tone may then unexpect-edly stop instead of changing over to theexpected constant tone. The sensors cannot detect high objects, such as projecting loading docks.
• In such situations, pay extra attention andmanoeuvre/reposition the car particularlyslowly or stop the current parkingmanoeuvre - there may be a high risk ofdamage to vehicles or other objects sinceinformation from the sensors is notalways reliable in such situations.
IMPORTANT
In certain conditions the parking assistance system may produce incorrect warning sig-nals that are caused by external soundsources that emit the same ultrasonic fre-quencies that the system works with. Examples of such sources include horns, wet tyres on asphalt, pneumatic brakes andexhaust noises from motorcycles, etc.
Maintenance
Location of the parking sensors 24
.
For parking assistance to work optimally, the parking assistance sensors must be cleaned reg-ularly with water and car shampoo.

Parking with Active parking assistance *
The Active parking assistance (Park Assist Pilot - PAP) helps the driver park in three steps. Thefunction can also help the driver to leave a park-ing space.
NOTE
The PAP function measures the space and steers the car - the driver's task is to:
• keep a close watch around the car
• follow the instructions in the centre dis-play
• change gear (reverse/forward)
• control and maintain a safe speed
• brake and stop.
PAP can be activated if the following criteria are met once the engine has been started:
• No trailer is attached to the car.
• Speed must be lower than 30 km/h(20 mph).
NOTE
The distance between the car and parking spaces should be 0.5-1.5 metres while PAPis searching for a parking space.
ParkingThe PAP function parks the car using the follow- ing steps:
1. A parking space is identified and measured.
2. The car is reversed into the space.
3. The car is positioned into the space - the
system may then request that the driver changes gear.
Finding and measuring parking spaces
The function can be activated in the centre display's functionview. It can also be accessed from the camera views.
Principle for parallel parking.
Principle for perpendicular parking.
1. Drive no faster than 30 km/h (20 mph) forparallel parking or 20 km/h (12 mph) for perpendicular parking.
2. Tap on the
Park In button in function view.
> PAP searches for a parking space and checks whether it is big enough.
3. Keep an eye on the centre display - be ready to stop the car when the graphic and mes- sage indicate that a suitable parking spacehas been found.
> A pop-up window is shown.
4. Select
Parallel parking or Perpendicular
parking and select reverse gear.
